Overview
The NCP114AMX090TCG is a high-performance 300 mA Low Dropout Linear Regulator (LDO) produced by ON Semiconductor. This device is designed to provide a very stable, accurate voltage with low noise, making it suitable for space-constrained, noise-sensitive applications. The NCP114 features dynamic quiescent current adjustment, which optimizes performance for battery-operated portable devices by minimizing power consumption at no-load conditions.
